Hey there,

Okay so for inverse equations I use the method in which you switch the variables and solve for y.

So the equation y = 100 - x would look like:

  • x = 100 - y

Now we solve for y in this equation:

  • x - 100 = - y

Since the y is negative and we are solving for a positive we divide by -1 on both sides:

  • -x + 100 = y

So the inverse of y = 100 - x would have to be -x + 100 = y.

Hope I helped,

Amna
